Force & Motion, 5.P.1.1 & 5.P.1.4

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is friction?

Back

A force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What happens to an object when no net force acts on it?

Back

It will remain at rest or continue to move at a constant speed in a straight line.

Front

What is gravity?

Back

A force that attracts two bodies towards each other, such as the Earth pulling objects towards its center.

Front

How does mass affect the motion of an object?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F=ma).

Front

What is a satellite?

Back

An object that orbits around a planet or another celestial body.

Front

What happens to a satellite if it moves too slowly?

Back

It will fall back to the planet due to gravity.
